Arrange them, 5 cm. apart in a tray greased with butter.

Grease the pieces surface with whisked eggs.

Wait until the pieces are double–sized.

Put the tray on the middle grid of a very hot oven for 15 minutes until the pieces are of golden color.

Switch off the oven, open its door and keep the tray inside for 5 minutes.
